Unfortunately, we have no information on arrival time for specific products. It is not advisable to add out-of-stock goods to package, and because it may take several months for them to arrive. Not unlikely, out-of-stock goods will be excluded from sale.You can place separate orders. One specifies only available items, and the other one specifies out-of-stock items.

In order to automatically reserve a currently out-of-stock item upon its arrival, you should place an order and pay for it.

The FrSky ASS-70 Air Speed sensor is designed for use with FrSky Smart Port enabled systems and provides valuable airspeed data in real time via the FrSky telemetry system.

Supplied as a simple, plug and play system, the sensor takes air pressure data from the pitot tube via 2 flexible silicone tubes (one from the pressure port and the other from the static port) and sends the data to your FrSky transmitter via your Smart Port equipped X-series reciever.

For accurate airspeed measurement the pitot tube should be located in clean airflow, well away from propeller wash and exhaust residue.

This sensor can be "daisy-chained" together with other FrSky telemetry sensors such as battery voltage, current, RPM, variometer and GPS to provide a complete data package.
